Description

Design Features

Designed for high-performance alignment and assembly

0.5 nm closed-loop resolution

Fully preloaded air-bearing

Low-noise linear amplifiers

Complete noncontact design

Overview

ABL1000 series stages are the highest performance miniature air-bearing stages available. Aerotech has combined industry-leading motion control and positioning system experience with the latest technologies to produce a truly outstanding miniature, linear air-bearing stage.

Linear Stage

The linear positioner is a fully preloaded, noncontact design. Inherently frictionless, air bearings have proven to be the standard in precision applications. Driven by a noncontact linear brushless servomotor, this stage proves the ultimate solution whether the application requires small, accurate steps or constant smooth velocity. Superior magnetic field and motor coil design result in the highest force output of any miniature air-bearing stage. This stage offers superior servo performance and features a robust and perturbation-free cable management system.

Feedback and Control System

A wide selection of state-of-the-art controllers are available along with a variety of high-performance linear and PWM amplifiers.

Options

Convenient rack or panel-mount amplifiers are offered with all systems. Aerotech’s expert technical staff is experienced in custom system designs and will work with you to generate a system to meet the unique needs of your application.

Maximum speed based on stage capability; maximum application velocity may be limited by system data rate and system resolution.

Max load for XY configuration is 10.0 kg.

Values with Aerotech controls and -PL2 metrology option.

Dependent on flatness of stage mounting surface.

To protect air bearing against under-pressure, an in-line pressure switch tied to the controller E-stop input is required.

Air supply must be clean, dry to 0° F dew point, and filtered to 0.25 µm or better; recommend nitrogen at 99.99% purity.

Integration (Required)

Aerotech offers both standard and custom integration services to help you get your system fully operational as quickly as possible. The following standard integration options are available for this system. Please consult Aerotech if you are unsure what level of integration is required, or if you desire custom integration support with your system.

Option

Description

-TAS

Integration - Test as systemTesting, integration, and documentation of a group of components as a complete system that will be used together (ex: drive, controller, and stage). This includes parameter file generation, system tuning, and documentation of the system configuration.

-TAC

Integration - Test as components Testing and integration of individual items as discrete components that ship together. This is typically used for spare parts, replacement parts, or items that will not be used together. These components may or may not be part of a larger system.
